   Ava ERP Training Portal — design system
   Aligned with AvaERP design.md v2.3 (dark-only, oklch tokens,
   amber accent, status palette) with intentional deviations for
   a video-first marketing/learning surface:
     - button heights 36 (sm) / 48 (lg) — lg for hero CTA
     - H1 marketing scale 32–56 px instead of 16 px page-title
     - airy layout instead of ERP density
